Dies when hot no spark carb gets gas plugs are dry start when cool

sometimes when a spark plug or the coil is going bad it will run till it gets hot then die. after it cools off it will start and run fine. till it gets hot again. replace the spark plug if that don't fix it you may want to start looking for a coil.

Hi Charles:
I'd start by checking the spark plug condition and function.
Wet........... no spark
Dry............ no fuel
Check for spark anyway. Hot and blue.
Try priming carb with a squirt of gas.
Drain and flush carb. You may need to remove and thoroughly clean if gummed up.

Hi Lennard:
Cars and trucks section but CR80 sounds like a motorcycle. right?
You need two basic things:
1) Spark - pull the spark plug, connect the lead, hold against the head, and spin it over. Spark shoulld be hot and blue.
2) Fuel - Drain tank and fill with fresh gas
Drain and flush carb
If it has a filter, make sure that fuel is flowing through it.
Try a "normal" start........... choke, kick over 5 times. If no start, remove plug and check for fuel in cylinder. Wet plug means no spark. Dry plug means no fuel.
If dry plug try priming the carb (give it a squirt of gas with choke off)
It should try to start.
To let me know how you're doing, reply as a comment on this post.
Cheers.

Sounds like fuel pump probs if you have no spark.

could be the coil getting hot and loosing spark

being that would be a twin cylinder engine and has two sep coils does it missfire before it dies?does it have spark when it dies?does it sputter then die like it runs out of gas where the cap vent could be plugged and it vapor locks if you spark carb cleaner or starting fluid the solenoid on the bottom of the carb shutting off that should give you something to start with

Clean carb. Pull apart and soak in carb cleaner. Blow dry with air nozzle. Make sure air filter is clean and plenty of air. Make sure spark plug is not gapped wrong and running to hot. Make sure oil/fuel mixture is accurate

A.dirty fuel line/filter/trash in carb B. bad coil C. carb too rich/carboned out spark plugs.D. short in the switch wires

It sounds like you may have 2 problems

• Bad gas
• dpossible loose spark plug( bad compression)

Solution

dump out the gas put new in
Remove the spar plug and examine the plug if it is wet and black it is fouled
if it is white ad dry it is not getting gas

If you can replace the spark plug if not just clean it with a wire brush put back in and tighten

Finally make sure the spark plug wire is not lose

Best of luck to you

Similar experience with the same blower. I cleaned the carb checked for spark but I still can't get it to start
