Title: 88 Sammy, No fuel through carb
Post by: Batman7349 on November 11, 2009, 03:56:17 PM: New fuel pump working fine. Fuel into carburetor, but will only run when primed with raw fuel into venturi. No fuel from accelerator pump, and apparently no fuel through main jets. Is there a anti diesel fuel cut off that might be bad, or just a crappy Hitachi that has sat too long?

There is 'computer control' of that carb. Check connections and that the computer is getting power. If you have a buddy with a spare unit or vehicle try doing some troubleshootin by swapping.

Good luck, Eric

I removed the parts needed to get to the elbow the fuel line hooks to off. I sprayed carb cleaner into the hole the elbow came off of. There is small screen filter inside that can get plugged. Also the float can stick shut. I also took off the level window and sprayed in there too. I put it back together and it fired right up. Hope it helps.

And cut in a 2" exhaust (thrush turbo 30 bucks from A zone), 7' tail pipe ($13). vcMan these sammi really screams now. Yoiu better hold on when the secondary kicks in. Next year maybe a RV 2 cam, calmimi header

Good luck on your hightachis
