Advice and ideas required

Just finished refurb of inside of chim .(pics to follow shortly) chim has been of the road for 6 weeks. Started first time last night for test drive after recharging the disconnected battery. About 17 miles in smell of petrol in cab and a loss of power and lots of miss fires, within a few seconds it passed. Though dirt, ignore it. Then drove car home today, 60 miles into journey happened again. Strong smell of petrol in car, then sudden loss of power, lots of miss firing sounds under the engine, again dropped down a few gears, and within a few seconds cleared and power returned. Any ideas anyone?

Sounds like a temporary fuel leak to me causing loss of fuel pressure (and power).

You'd best get it up in the air and check the condition of all fuel lines and hose unions. It might be happening in the engine bay area so pay particular attention there as this has been the demise of some poor Chims - high pressure fuel + hot exhaust manifold

If that all checks out fine then a leaking injector could also cause this.

How noticeable is the loss of power? One cylinder's worth? (noticeable but still very driveable) Or does it feel like the whole engine is dropping out?

It feels like the whole engine is failing to be honest

In that case then I'd guess a fuel leak somewhere on the main fuel line/rail if it's bad enough that the whole cabin smells of petrol and the engine looses significant power.

I'm guessing engine bay area as if it was anywhere else you probably wouldn't smell it so well whilst on the move.

Next time it happens, pull over straight away and pop the bonnet and see if you can see any stray fuel although TBH, with a possible fuel leak in the engine bay you really want to get this sorted with zero/minimal driving for obvious reasons!

Good luck - hope you get it sorted!
