    thanks, bike runs okay in one sense, covered 25 miles, backfiring on the way, but not all the time. Bike has been off the road since early december, although I do start it and let it run. I can't get to a bike shop till tomorrow.

Check to make sure your plugs arent fouled. the last bike i had did that to me, fine in the morning and when i went to leave for work in the afternoon the bike ran like **** for a few seconds and shut off. i took the bike back to where i bought it and they replaced the plugs. ran fine after that.

Backfires at idle (sometimes) but seems through air intake not exhaust ? Bike struggles to start without choke when warm ??

A bike that backfires through the carb has ignition timing that is too far advanced. This will also cause bad starting. Get the timing fixed.

Bajaj pulsar 180 dtsi backfiring while starting? why? and missing after starting.

check first if all cylinders spark plugs are firing, seem like you are missing on one cylinder. this will cause as well backfiring.

if this is not the case then:

backfiring can be caused by too rich fuel mix or by wrongly set advance. there is unburnt fuel present in exorst and this cause backfire. these two are most "popular" causes of the backfiring.

hope this will help you solve the problem, do not forget to vote...

I have a craftsman LT 2000 22 horse, the engine sounds like it's struggling and bacfires?

Probably a fuel issue. Backfiring is usually a timing or fuel issue. One can cause the other. As this is an engine issue, please post model and type.

Struggle to start my car in the mornings

Check condition of air cleaner, spark plugs, fuel filter and timing. Routine maintenance will rule out the obvious, after that you can look for other reasons if the same condition continues.

Backfiring, flames coming out of exhaust and cutting out

Sounds to be a timing problem or burnt exhaust valve.. A compression test will tell the story.
