Does my vac attack 2 need crank case oil? - Homelite Leaf Vac Attack

You need to take to shop and have them check it out, more than likely the cost of Repairs will exceed the price of a new Blower, In other words Yes this Motor is NO GOOD . Sorry For the Bad News..

go to www.ereplacmentparts.com for a diagram. just pay attention when taking apart. its not hard. even lable parts if you need to. an air compressor will be useful in cleaning. and brake cleaner does good on oily parts.drys quick and leaves no residue.

Your manual states it is 50:1 which is 2.6 ounces of oil/gallon of gas...or 1.3 ounces in 1/2 gallon of gas. This is a common ratio for Homelite 2 stroke engines. I recommend synthetic oil.
Specs are on page 8 of your manual.

fit new pump ad float diaphragms in the carby
the fuel mix has become irrelevant as Stihl have an oil that is a 50:1 oil and covers all ratios and mixtures
do not use any e-mix fuels as that destroys carby components

My Homwlitw Attack ii won't start. Spark plug is dry even after priming more than 10 times. Where so I start? Thanks, Fred

Yours is not a current model and I did not find a manual. The following is an excerpt from a 26cc MightyLite Blower/Vac UT08550/UT08951 "Operator's Manual":
This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean 1 gallon container approved for gasoline.
Recommended fuel: This engine is certified to operate on unleaded gasoline intended for automotive use.
Mix Homelite Premium Exact Mix lubricant with gasoline according to the instructions on the package. If Premium Exact Mix lubricant is not available, use a high quality synthetic 2-cycle engine lubricant, mixed at 2.6 oz. per gallon (US).
Do not use automotive lubricant or 2-cycle outboard lubricant.
NOTE: Premium Exact Mix fuel mix will stay fresh up to 30 days. DO NOT mix quantities larger than usable in a 30 day period.
PREMIUM EXACT MIX (50:1)
GasolineLubricant
1 gallon (US) 2.6 oz.
1 Liter 20 cc (20 ml)

1 quart fuel:3/4 ounces of oil = 1 Gallon fuel:3 ounces of oil or slightly less than 43:1. Not what a current manual recommends.
If properly adjusted your blower will operate fine on 50:1 regardless of what the manual reads. HTH

Yes it will use a fuel mixture of 40:1(3.2 oz of two cycle oil to 1 gallon of gas). Any fuel sitting over 30 days now is considered bad fuel. All the manufacturers schools this year and told us this. We are finding it to be true.
Good day.

The mix that I would use is one ounce of two cycle oil per quart or four ounces of two cycle oil per gallon of unleaded gasoline. Hope this helped and best wishes.

Hope this helps if you're still looking.
