running on gas and reeving high

[ChunkTB42]

recently brought a tb42 the petrol dosent work still working on a solutions but when i use gas it reevs high around 1600-1800 just wondering if this is normal for gas.

Welcome to the forum. No the high revs are not normal at all. Is it EFI or a carby? Long periods of using LPG, dries out the rubber components, especially in a carby.

its EFI the revs have gone down a bit

Sounds like a sticky linkage to the butterfly. I have the idle speed on my RB30 up a bit more than normal, but it should be in between 650-800 rpm.

I've a had a bit of a search, but can't seem to find the exact figure.
