  1. I watched your video on the first start up and it was running on six, I think one of two things has happened either the valve stuck slightly due to slight corrosion, lack of lube or possibly insuffiecent reaming of guide on rebuild and is now bent from a tap from piston or the valve seat has dropped out of head, due to overheat or two much clearance, I guess it is a bit late to suggest not to run it... I would think you would have no more than a slight dent in the top of the piston and just need to fix the valve.

     

    Many Thanks for that. I'll let you know what I find..... will be a couple of weeks before I get chance to remove the head.

  2. I would check compession pressures first to narrow the problem down to a cylinder. Also, if it was a valve not seating, it may have "kissed" the piston and be slightly out of line, ie. bent.......

     

    Of course, it may be too obvious, but are you sure it is not a duff spark plug? Even if new they can fail under pressure, hence why it might sound OK on starting.

     

    Richard.... Compresion test shows No 3 Cyl well down (45psi) all the others are around 150psi -- so definate valve issue !! Regards Paul

  3. Operation Gate... Get Abbot To Evesham

     

    Filmed in 1994. Abbot (03DA30 - believed a prototype) was purchased from Jacksons and had spent some time at a friends Garden Centre, where there was a bit of space to drive it. It was in pretty good condition with a new powerpack... looked as if it had been overhauled recently. I decided to move it to covered accomodation to complete the restoration... mainly just painting. I got a good deal when i purchased it as it sometimes would not start... this turned out to be the starter motor which was loose ! However prior to the move the starter would not engage at all. Friends rallied round and a Diamond T turned up to give it a bump start....

     

    See the video on youtube..

     

    More videos to follow.. including power pack removal - to sort starter motor.

  4. Before doing anything too radical I'd check the fuel filter again. If you've not got much fuel in and it's picking up all the crap in the tank you might end up going through 3 or 4 of them before it gets clean...

     

    Thanks for that.... I have previously removed the commanders seat mount.... which is basically a 12inch access cover in the lower fuel tank. There was very little sediment etc in there. All the 13 year old fuel was removed and fresh fuel put in. The fuel pressure at the carb is fine.

     

    Anyhow events have moved on... compresion test yesterday revealled No3 Cyl at 45psi... with all the others around 150psi... so stuck valve.

     

    Frustrating as the engine seemed to run fine when starting prior to any road use... see following two short videos.

     

     

     

     

     

    Both of these runs were with fresh fuel gravity fed from a small tank.

     

    However....

     

    I initially, for some stupid reason, left the old (13yrs) fuel in the tank for the first proper short road runs. This certainly seemed to leave a very lacquer like deposit inside the new carb. I then replaced the carb and removed all the old fuel. Could this fuel have gummed up a valve in the few short runs.. I think it is possible. Will try a fuel additive before anything alse.... worth a shot.

     

    Chris ... thanks for your response also.

  5. Major rebuild over last 14 months. Ex Witham J60 fitted - which appeared to run fine before it was fitted into vehicle.

     

    Most engine ancillaries are new... HT Leads, Coil, distributor etc. Had new carb... which i have replaced with another new carb... to eliminate fuel issues. New fuel pump, lines and filter.

     

    See video on youtube taken today. Goes quite well considering its probably running on 5 cyls.

    I'm thinking sticking/dropped valve... so compression test next.

     

    Any ideas guys....:nut:

  6. Nice video :D

     

    The DVLA entry for AAB 960A says 'NO BODY TYPE DEFINED' so it seems to me the overall theme is not to fill in all the bits of the form...?

    When I registered my CVRT Striker recently the Guy at the licencing office went through the form with me. He was unsure about what to put as body type... he showed me a list of options.. none of which really applied... the nearest one that seemed sort of logical was "special mobile unit" so this is what we went for !!!

  7. Can anyone help ?

     

    I have a client who wants to hire a Tracked, Armoured vehicle (and Driver) for a couple of hours (11.00hrs ish) on the 16th June.

     

    Location: Near Betws-y-Coed.

     

    vehicle to be driven along a short forest road to deliver my clients to a "Outward Bound" style corporate team building event.

     

    They will pay whatever costs are required - transport etc.

     

    Originally they were going to pay to transport my CVRT Striker from the Midlands to Wales.... BUT I now cannot do it for them. There must be someone more local to Betws-y-Coed who can do it - hopefully.

     

    Call me (07879 811130) or email for further info.

     

    Thanks Chaps

    Paul
