Homelite leaf blowers that use whats called a half crankshaft system are prone to many problems. Whats a half crank system you ask? If there is a small aluminum plate that attaches to the side of the engine by the gas tank you have one of these. Usually held on with 4 small bolts. I just got rid of a Homelite Vac Attack 2 that had spark and compression but the compression checked low about 75 should be 90 or better. What happened, a head bolt came loose and the engine ran lean causing the fragile rings on the piston to heat up and when that happens they loose their outward spring that seals against the cyclinder walls. A simple compression check using a gauge and not your finger will tell you that. Other causes could be less than normal spark, or maybe the exhaust port under the muffler has carbon build up or the muffler is plugged up also Check all bolts, and nuts to make sure they are tight.

NOPE You can buy new cheaper than have this one repaired, Also I don't recommend using these for a vac on leaves. Leaves are very very dirty and these blower vacs usually dont last long when used as a vac. The seize problem was from an improper fuel mix. THE next one you getone use a little more oil, than says in the owners manual. Like if it says 50/1<<>> mix 40/1 more oil will just foul the plug and oil the muffler,but you will not have a seizure problem. I have never had a problem with a 40/1 mix .

Hello,
Most Probably the problem lies in the adjustment of the carburettor. There are two needles in the carb one for lowend adjustment and one for high end adjustment. Your lowend adjustment seems fine. The highend needle needs to be adjusted. Following are some very detailed procedures for adjusting these types of carbs

If your machine has a carb other than a "Walbro" dont worry the procedures are same. I am sure if your engine has not completed its life span this will solve your problem.
