As title says, Hesitation When Taking off (Fine if Revs are over 1k)

Any suggestions to what it maybe?

Thanks

Hello, Natopatrol, and welcome to the forum. Please head over to the introduction section and say g'day. What sort of engine is it, RB30 or TB42?

[Natolpatrol]

Hi mate, its a TB42

Get a full tune carby tune as well as it s either over fueling or running too lean

Yeah Ill get that done. When the choke is out so it idles above 1k (well at 1k), its fine, Like when putting your foot down it will decrease in revs then pick back up or either stall, but it does not do that at 1k revs.

Sounds like your idle jet might be blocked

If your running dual fuel ,I'd say the carbie is dry from gas use.
suggest the same as P93 has stated

Hi mate its not dual fuel. Might get some carby cleaner and see how that goes.

Otherwise put a kit though it

Think i may have found the problem, the two hoses coming from the top of the engine(rocker Cover) Was basically fucked, big hole in one and big split in the other. Although not sure if that may fix the problem waiting for them to arrive. Iv seen on another forum that he had the same problem and it was fixed, when he noticed the damaged hoses.

sounds like a cheap fix then well done

The one going down between the manifold and block - goes to your pcv valve.

[Natolpatrol]

You mean the one that goes to the inlet-manifold? One goes to the inlet and one goes to the airbox. Im not sure what a pcv valve is but ill google it and check it out.

I have this same problem in my efi dual fuel crappadore, better check some hoses 2morrow

[Natolpatrol]

Well that didn't fix it, idles much better though. Still have the problem, seems like its sucking in to much air, goes to stall when pressing the accelerator in then picks up revs (sits at 800, use accelerator, goes to stall then revs pick backup).

Guess ill put it in the shop next week.
