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.

I do not know the oil-to-gas ratio to mix/buy. My husband passed away, and I cannot find the manual. Help, please. THANK YOU


Can you find the model number on the Homelite Mighty Lite BlowerVac?

For the UT08520 and UT08921 26cc blowers and the UT08550 and UT08951 blower vacs, you can mix the Homelite Premium Exact Lubricant with gasoline following the label directions. For other synthetic oil additives, use 2.6 oz of additive per 1 gallon of gasoline. (It's 20ml to 1 l if you use the metric system.) That's a 50:1 ratio (gasoline to additive).

Many Homelite Blower manuals are available here: http://manuals.homelite.com/documents?page=5 . You should try to find your exact model and then check the manual to confirm that your model blower vac uses this same ratio of oil to gasoline. You will need Adobe Reader or a similar program to read the manual.

I hope this helps.

I just need a manual for the Homelite Mighty Lite Gas Powered Blower Vac.


Do you have your model number?

You should be able to find your manual on this site:

http://www.homelite.com/service_support/product_owners_manuals


The manuals are listed by their model number rather than their marketing name. Look for the serial number plate which should also have the model number.

Thank you for using FixYa!

I have the homelite Vac Attack 2, i'm having trouble starting it, i prime it the desired 7 times (actually more) but i just sit there and pull, and pull, and pull the cord....really getting frustrated!


#1 senerio
Fouled spark plug
ie, carbon and or fuel fouled
install new plug, and withouth choking or priming, pull 4-6 times while holding the throttle at wide open.

If not fouled, go to senerio #2

#2 senerio
Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
5) replace gaskets/diaphragms
b) use a spray carb cleaner to clean jets, holes, and body of carb

I have a UT08580 Mighty Lite backpacker blower with a missing spark plug, I need to know what plug goes in it.


The Homelite part number for this spark plug is 870174001. This number crosses to Champion spark plug RCJ6Y which can be bought at any Home Depot, Lowes, Ace Hardware, etc for about $3

It sounds like your blower needs a carburator overhaul. Either there is gum from dried gas blocking a passage, or one of the diaphrams has a crack in it. This is not a difficult repair. You purchase a carb kit for your machine, then carefully disassemble the carb & clean all of the components with brake cleaner spray. Make sure to spray through the several tiny holes in each diaphragm chamber. Now put the carb back together, using the new parts in the kit.
Before you do this, however, check the hoses on the engine, one might be cracked or blocked.
