Any Small Engine Repairers Here?

[wm460]

I am looking for a small engine repairer, or some one with the knowledge about Sthils.
I have a Stihl HS 74 hedge trimmer with a buggered carby.
A while ago I was given a Stihl BG 72 blower the motor worked but the plastic casing was stuffed.
They are both approx the same age.
My query is will the blower carby fit the hedge trimmer?

If you remove both carbs there are model numbers on them check they are the same. If not as long as the carb on the hedge trimmer is not damaged as in broken then a carb gasket set should help to make sure that it is cleaned. Any old 2 stroke oil if it was left with some in may have become gummy and block things up.
That was a number one repair after winter storage where people left fuel in there.

I got the hedge trimmer from work, the maintenance supervisor had taken it to the local shonk to repalce the carby.
See how he used bog where the fuel lines connect to the carby, It leaked when went back to work, got worst as time went by, when the workshop was stunk out by fuel the supervisor condemned it. I claimed it, thinking one day I will take to a sthil dealer and get a new carby for it.
Today I went into my former chook house I saw the old blower I thought may be it will fit the hedge trimmer.

May be easier to get another carb on e bay not a good repair.

Was it leaking from the fuel inlet to the carb or from the gasket at the joint or even are the screws loose(OK I know most of us have a screw loose), you will need to take that carb off and clean it up and inspect it.

In a similar boat.
A dark gardener put straight petrol into my brush cutter. Lasted about 10 min and then solid,
That model is no longer available and no spares off the shelf.
Hunt for spares or buy a new one.

Depending on the make try searching on E bay for a new pot and piston as that is normally what siezes when straight petrol is used

Thanks Derek for the suggestion,
In darkest africa ebay is not a good alternative.
Get ripped off or wait 6 weeks for delivery.
Never know if it will be the right parts.
A new machine with 2 yr warranty is a better bet and get it the next day.

I had to laugh reading this post. A few years ago My son and I were on a SCUBA diving trip in the Caribbean. We usually do self-led shore dives to save money and see if we really would save each other in a pinch... But this day we splurged and booked a trip with an outfit that used a retired USA Military high speed pontoon boat, twin engines fully enclosed if the boat gets swamped/submerged. Apparently while fueling up that AM, the attendant filled it with regular gas vs diesel (must have been a chore with the different nozzels). The trip lasted about 100 yards from the dock... I checked in 6 months later and the owner said it cost $60,000 USD for the new engines.

Did the owner shoot the attendant ?

After a lot of stuffing around trying to get it to fit, I will buy a replacement carby.



Any one know what it under black plate where the fuel line goes into?

Started to leak from underneath it.

Normally a gasket and another with cut outs. If you take them apart then take note of how the different gaskets are orientated if you replace them wrongly it definitely will not work and fuel may leak everywhere. As well as noting which order they come out as that is also important.

If you strip it down completely then the two adjuster needles will need to be reset I found that screw them both in fully then back them out 3/4 of a turn this gives you a good starting point. When adjusting them from there small adjustments are only needed. the idle screw is slightly different to set up when it is screwed in the taper on the end will contact a lever, start by screwing it in until it just touches the lever and then unscrew it by 1 turn and again work from there with small adjustments.

A new carb should be set to approximately the correct setting and require very little adjustment
