Hi,

I have a old Fiat OM BI20CL with LPG, Impco VFF30 filter, cobra regulator and impco model 100 mixer

The forklift was running well some strange things arrived.

First the forklift wouldn't start because the regulator was clogged with tar, the filter and the regulator were redone. but it was hard to get going again.

It worked a bit like that, then we redid the timing belt, put everything back together, it started, we moved it a bit, then it couldn't start.....

After a few days, I searched, and I managed to restart it by playing on the pipes, I put the mixer in an ultrasonic bath and it started.

I used it for 2 days and it still broke down. here's the situation today.

So I tried with another VFF30 and cobra system that I was lent (not new) and the same thing.

It wants to start but doesn't hold, I have a good spark at the spark plugs which are new, the timing is correct, the vacuum pipe sucks well.

I'm a bit lost, I wonder if I should not change the VFF30 and cobra with new ones?

If you can help me?
