Crossfire 150 hiccups off idle.
Every time i punch it off idle it "hiccups" Will also do it if i punch while just cruising at a steady speed. Best way to descibe it is it feels like i hit the kill switch for a split second. So....punch throttle...hiccup....haul ass....smooth as butter till i let off and punch it again.
Checked carb...new intake just incase...fuel flow is good...im kinda stumped. It did this last year and i cant for the life of me remember what i did to fix it. Changed coil and it stopped for a couple of hours and started doing it again. |
What kind of carb? (although you said it went away after a new coil?)
What coils are you using? Cheap ones don't last long. (buy a quality coil) |
Its a 26mm cv (only one ive ever seen) been on for close to a year no problems....cant remember if i had this carb on last time it happened or if it was a 24mm. Coil wise ebay one....Ill try another coil tomorrow.
|
Ebay cheapy coils are problematic. Might be the problem,
CV carbs use the elec choke, right? Make sure yours isn't stuck. |
Choke is blocked off. have tried coils off other running buggys and a couple of different carbs off good running buggys......Im at a loss.
|
Different carbs and coils? Same result?
But it disappeared for a while after you replaced a coil before? |
Yep same results....and yep maybe it was just a coincident that it didn't do it after i changed coils the first time....its getting worse now also....maybe its just a bad harness...anywhere to buy the engine harness other than BDs 80 dollar hand made one?
|
Not sure on the harness.
Any chance of you getting a video of the problem? Getting worse is actually good. At least it makes it easier to identify as opposed to sporadic problems. |
i got a video but no clue how to upload it unless i link it from facebook
|
do you use rollers or sliders in your variator? have you checked them lately ? maybe they could be warn ?
|
Sliders and its been a few months since ive checked them. But i did have the carb off last night and the intake valve was open and i could see that the exaust valve was like a brick red color.....Could a burnt valve cause this?
|
Would most likely cause poor compression if it was burnt.
What is your compression? |
195psi
|
Don't think your valve is burnt with that hi of compression.
Have you checked your valve clearances? Have you checked your valve/camshaft timing? Have you checked your cam chain tension? Checking your sliders is probably a good idea too. (may have had one flop over) Maybe check the clutch, bell, and belt. You might be slipping Lastly, can you try a different CDI just for the Hell of it? It almost sounds like a timing issue. (which is why I want you to look at valve timing) |
Have tried a couple different cdis. Valves are adjusted. Ill check timing etc. clutch bell and belt are good but ill check sliders.
