Mass of 18 is 80; Mass of 12 is 40.
Solution is
1) M18+M12=M16, given as 120
2) Mg16=16.24x120=80
3).75M18+.5M12=80
(mult by -2)

### I have a husqvarna 435 with I believe a 16 inch bar. Can the bar be replaced with an 18 inch bar?

Yes, as long as the replacement bar's oil hole lines up, and you get the right length chain. From memory Huskies are compatible with many other/generic bars.

### Poulan 2550 18

There is no problem as long as the bar is the right bar and the new chain you use is the right pitch for the sprocket that is on your saw.

### 2550 18

No problem at all. Just need to make sure the two studs attaching the bar to the motor head fit correctly. Of course, the former chain is now too long. Either have a saw shop make you a 'loop' to fit, usually \$1/inch of bar=\$16 for your new setup, or try a prepackaged chain labelled for the 16 inch bar. I recommend the former, because then you get an expert to look over your new setup for you. Shop chains are usually better quality, always fit correctly, and cost no more, often less, than department store chains

### I have antique womans gold nugget bulova watch with 014ko and 890643 on the back of the watch should I throw this away

Don't throw it away! Bulova have a good reputation. It ma not be worth much, but you have the serial number and the 14k probably means it's 14 carat gold. 14 carat old is the highest quality used for watches (18 carat is too soft for everyday wear) I used to work for Shackman and we made watch cases and bracelets for the major brands such as Omega.

Trysearching for Bulova watches on eBay then looking at 'completed listings' under 'advanced' after you search for some idea of value.

### I have a McCulloch Mac 110 mini-Chain saw that needs a new chain blade. I believe it's a 12 inch... anything else I need to know to go buy a new bade?

Hello Kip;
If the new bar is not the same size as the old chains will not fit. Count the drive links on your chain.

Oregon Bar & Chain Selector

I seriously doubt you saw needs an "Intenz" bar.
The Oregon part number you choose can easily be converted to a different bar manufacturer's part number.

If you have more questions or need additional help please reply below and I will get back to you. Thank you for using FixYa and Good Luck. HTH

### I would like to go down A bar size our two on my poulan wildthing

I have a Poulan Pro 295 20".  When I bought it I also bought a 16"bar and chain and have been using those since.  They make the saw much easier to handle and are a better match to the available power. The key dimension is from the bar's mounting hole to its end.  At the store look at the normal replacement bar for your 18" saw, and pick out a 16" or even 14" bar with the same dimensions there.  This can be easily seen by laying one bar over the other.
